Electrical Faults

In the event of errors in the signal levels on the communication cables for the central electronic module a diagnostic trouble code (DTC) is stored in the central electronic module. A check is carried out on each communication cable to the central electronic module, CAN L, CAN H on the low speed side and CAN L and CAN H on the high speed side There are two different levels which are detected (low or high).

This gives eight diagnostic trouble codes for detecting electrical faults.

The diagnostic trouble codes for electrical faults are CEM-DF0X for the low speed network and CEM-DF1X for high speed network.
